Title: Apparatus for shaping the base of cans or the like
Inventor: GOEB CLAUDE
IPC: B21D51/26
Filed: 1984-12-11
Abstract: The invention relates to an apparatus for shaping the base of cans or the like and, in order to utilise existing machine parts, this apparatus is designed as an additional device to a can cutting and brushing machine and has a mandrel 5 serving as a counter-punch during the shaping of the can base and subsequently fed to the brushing station, a die 23 interacting with the said mandrel, and, if required, an ejector 24. The mandrel 5 for receiving the can 7 is arranged between the base-shaping tool 22 and a counterstop 9. The force required for the shaping of the can base acts on the mounting of the mandrel 5 or turret head 4 solely within the limits of the prestressing force of the spring 18, via the gripper system of the device.

Title: Trench sheeting designed for driving through by means of a driving shield during the driving of an earth tube between a starting shaft and a target shaft
IPC: E02D17/04
Filed: 1985-03-05
Abstract: In order to be able to drive through the wall of a trench secured by sheeting during the driving of an earth tube by means of a driving shield, the sheeting, in the area to be driven through by the driving shield (25), consists of a prefabricated sheeting element (2), the width of which is greater than the outside diameter of the driving shield. An opening for the driving tube can be created in the sheeting element (2) by pulling a slide plate (8). A housing (19) can be attached to the sheeting element (2). A seal (24) acting against the driving shield (25) and a retaining device (23) containing a gripper are provided in the housing (19). Such a sheeting element can be integrated in conventional trench sheeting and permits in an especially simple manner the subsequent attachment of the devices necessary for driving through the trench wall. <IMAGE>

Title: Method for recording changes in the level of a pilot frequency signal
Inventor: FOHRINGER LOTHAR
IPC: H04B3/10
Filed: 1985-03-28
Abstract: A method is proposed for recording changes in the level of a pilot frequency signal which is transmitted via a cable path together with a high-frequency signal mixture. In order to be able to dispense with expensive filter means, such as bandpass filters, a power component is extracted according to the invention from the high-frequency signal mixture by means of a tap, is amplified if necessary in an amplifier and fed to a first input of a mixer. An oscillator signal with an essentially constant oscillator frequency (H1) and signal amplitude is applied to the second input of the mixer. The oscillator frequency is selected in such a way that a smaller mixing product (M1) is produced by mixing with the pilot frequency (P) than by mixing with the other frequencies of the composite signal. The smaller mixing product can be separated from the other mixing products by means of a simple low-pass filter. The level of the smaller mixing product then serves as a measure for the amplitude changes of the pilot frequency signal. <IMAGE>

Title: Agent for the selective removal of tumour cells with the aid of antibody-coated plastics
Inventor: MUELLER-SCHULTE DETLEF DR
IPC: A61K35/12
Filed: 1985-04-03
Abstract: Agent for selective tumour therapy consisting of a separating system which makes it possible to remove tumour cells from transplants or other extracorporeal liquids. The surface of the plastic separating system is chemically coupled to a tumour-specific antibody, an antitumour antibody or a tumour-specific active factor. The tumour cells are selectively bound by the tumour-specific molecules located on the walls of the separating system, which makes it possible to remove these cells from the normal cells.

Patent DE-3617983-A1 (DE)
Title: Connection of motor vehicle drive or output shaft sections
Inventor: SAMMER ADOLF
IPC: F16D1/033
Filed: 1986-05-28
Abstract: In a positive and non-positive connection of two aligning drive or output shaft sections of motor vehicles, the forces necessary for the torque transmission are for the most part applied through positively interlocking coupling elements arranged on the respective shaft section, as far as possible reducing the number of screw fasteners. The screw connection is essentially designed to secure the axial jointing of the two shaft sections thus connected to one another. In contrast to hitherto known solutions, therefore, only one or very few screw fasteners are now necessary. As a result, a rapid releasing of the connection of the two shaft sections is possible when necessary.
Patent DE-3622290-A1 (DE)
Inventor: DIRKS FRIEDRICH
IPC: B01D53/77
Filed: 1986-07-03
Abstract: A process for purifying flue gases by conducting the hot gases through a dry purification stage, and then through a pebble bed evaporator containing pebbles and a liquid. The flue gases then exit the pebble bed evaporator and are washed in a wet washing step. Waste liquid containing dissolved material from the wet washing step is then used as the liquid in the pebble bed evaporator; as this liquid evaporates in the pebble bed evaporator, solid precipitate forms on the pebbles. This solid precipitate is removed from the evaporator and is stored. Vapor from the pebble bed evaporator is condensed and used in the wet washing step. The purified flue gases exiting the wet washing step pass through a filter stage and are discharged.

Title: Method for the winding of threads
Inventor: SCHIPPERS HEINZ DR ING
IPC: B65H54/38
Filed: 1986-08-09
Abstract: In the method according to European Patent Application 86103045, chemical fibres are wound by step-precision winding, upper and lower limits as regards the traversing speed being varied in the same direction during the winding run. In addition to this, it is proposed that an increase should occur at the start of a winding run, this increase being terminated when the bobbin has a layer thickness of 10% of the entire layer thickness of the bobbin. As a result, the bobbin build-up is improved substantially and the number of faults during the run-off of the thread from the bobbin is reduced.

Title: Process and arrangement for removing nitrogen oxides from flue gases
Inventor: WEILER HELMUT ING GRAD
IPC: B01D53/86
Filed: 1986-08-09
Abstract: The flue gas to be denitrified, coming from a flue-gas desulphurization plant, is brought to a temperature of about 320 DEG C by a heat exchanger (4), charged with ammonia by a mixer (3) and fed to a fan burner (2). In the burner (2), the flue gas passes through a flame zone (22) and experiences a temperature increase of about 30 DEG C. In the fan burner (2), the ammonia previously added to the flue gas reacts, as a result of which the NOx concentration is substantially decreased. Downstream of the burner (2) is connected an SCR reactor (8) for the substantial elimination of nitrogen oxides. The flue gas exiting from the SCR reactor (8) is cooled in the heat exchanger (4) and in the course of this heats the flue gas to be denitrified coming from the flue-gas desulphurization plant. The heat losses in the heat exchanger are compensated for by the fan burner (2). <IMAGE>

Title: High-pressure cleaning device with foam generation
Inventor: OBERDORFER GUIDO
IPC: B08B3/02
Filed: 1986-09-08
Abstract: In the case of a high-pressure cleaning device with foam generation, in the cleaning medium there is provided a high-pressure pump, which takes in water from a water supply tank and, if appropriate, cleaning chemicals can be mixed with the water. The cleaning medium compressed by the high-pressure pump is fed via a line to a high-pressure spray device. To obtain simple foam generation, an air-carrying line is connected into the line on the delivery side of the high-pressure pump downstream of a foam injector, so that only compressed air is introduced into the line on the delivery side, while the chemical necessary for foaming is taken in by the high-pressure pump itself.

Title: Organometallic compounds of magnesium or lithium as pulverulent compositions, mixtures or adducts with clay
Inventor: PENTH BERND DR
IPC: C07F1/02
Filed: 1986-11-06
Abstract: To reduce the disadvantages of solutions of organolithium and organomagnesium compounds: owing to their ease of hydrolysis, the transport hazards of the highly or easily inflammable solvents, the costs of the solvents, the hazardous handling of the solutions due to danger of explosion and the inconvenience of working with such solutions, the process described brings the products into a pulverulent form which is less sensitive to hydrolysis, cheaper, less hazardous and easier to handle. For this purpose, the organometallic compound is applied to a dried clay in such a way that the surface of the product particles formed comprises predominantly clay.
